So I checked some more components. Looks to me like the steering shaft has play and this is possibly causing the noise (see video). On top of that the anti roll bar bushing are shot (pics), though I'm not sure if that's causing the noise (I tried prying at the roll bar with a pry bar at those bushings and there was no movement - maybe this is not enough though). I'll keep looking into this and update when I know more. WhatsApp Video 2025-02-17 at 23.59.43_50ba850b.mp4

Hey, just wanted to confirm my diagnosis before I proceed with repairs. 2006 Octavia with 170k miles. I'm trying to find the source of a clunk that happens only when stopped or at low speeds and moving the steering wheel in either direction - attaching a video to demonstrate. I've been able to produce a clunking sound by grabbing either front wheel at the 3 and 9 o'clock positions and shaking it back and forth; as best I can tell it's coming from the steering rack area. I pulled the tie rod ends off to see if it's the inner tie rod ball joint or the rack. I pushed and pulled on the inner tie rod and I see zero movement of the ball joint in its socket, instead it seems like the point where it enters the rack is moving up and down and making a knocking noise as it does that. See second attached video. At this point I'm thinking the rack is worn out and requires replacement. The car has seen a lot of short urban commutes so I'm thinking that's quite likely. I've seen some threads about adjusting steering rack preload such as this one. I've tried doing exactly this, but even with the preload set too high (steering wheel sticks a bit) the clunk is exactly as before. Does my diagnosis seem sound, is there something else to check? rack264.mp4 clunk264.mp4

Yeah in the video it's really only audible if you're wearing headphones and turn them up a bit. I did try moving the seat around, no change. Haven't tried with a passenger yet. Tried that, no change sadly

I can't seem to pinpoint the source of an annoying noise on a one year old 280 PS Mk3. The noise starts at 130km/h / 80mph and gets louder as the speed increases. I'm in Germany so these speeds are not uncommon. It's a kind of high pitched buzzing or rattling sound coming from the passenger seat (car is left hand drive). I'm attaching a video where it can be heard. Things I've checked: * center console (empty) * glovebox (empty) * under the seat, seat rails, between seat rails and floor - no loose items * styrofoam cover for module under the seat - removed it, wiggled it around, no change * passenger door pocket (empty) I don't have a passenger and this only happens at high speeds so unfortunately it makes pinpointing this hard since I can't just listen for it precisely in the area it seems to be coming from. Has anyone had something similar or does anyone have suggestions on what to check next? noise.mp4

I've done the job now and I can confirm they are indeed N90991002, I measured them wrong. And yep Skoda7zap lists them correctly as well, thanks for that tip.

Hey, I need to change the right hand side driveshaft in my 2006 Octavia mk2 DSG BKD. I know there are several types of driveshafts/CV axles used on these models and as far as I can tell mine is "CV outer joint, tripod inner joint housing bolted to transmission drive flange" as Haynes puts it. Here's what it looks like: I know the bolts are single use and I need new ones, unfortunately my new driveshaft came with a new hub bolt but not the six gearbox flange bolts so I need to buy replacements. I've measured them and they're M8 and around 33mm total length. I've now spent hours searching and still I cannot figure out what the correct VW part number is. According to this parts diagram it would be N90991002 but that can't be right because it's an M10, not an M8. I've been able to find some M8's but then they're too long, 50mm for instance. Can anyone help me figure out what part number these actually are? Thanks

Turns out that both the clips the shop used (presumably came with new intercooler they installed?) AND the new clips delivered with my Gates boost hoses were not the right size, just a bit too small. I looked up the exact part number clips for my car, then based on that I found and bought Febi Bilstein 49756 and those fit perfectly.

I recently had a shop replace a leaky intercooler while away from home. On the drive back home I had one of the boost pipes next to the intercooler partially pop off on the highway. I've now gotten some new boost hoses in case it was because of wear on those tabs at the ends, but when I put them on I realized that it seems the clips are too short to be able to hold both hose tabs in place at the same time - i.e. depending on how I position the clamp either the top or bottom tab will be held in, but not both at the same time. This is with both the original factory clips that the shop reinstalled and with the clips that came with my new Gates boost hoses. Here's how I have the clips on: bottom (holds): top (doesn't hold) you can even see that the top isn't correctly seated by looking at it from the side - you see the top side protruding outwards from that slit it sits in while the bottom side is flush: I've tried pushing the hose all the way in and wiggling it around to no avail, so as far as I can work out the clips are just too short. OEM number for my car would be 1J0145769H, any other versions I could try? Sadly I can't really go back to the shop in question with this because this was on a trip so they're far away. I'm thinking they installed some weird intercooler with poorly made hose fittings. Also, on the other side of that hose (where it goes into the pipe towards the intake manifold) I have the same clip installed in the same way and there are no problems, no leaks, which makes me suspect the intercooler further.

Update - it's cast iron, there are markings on the top of the control arms: GJS-400-15

Hey, I'm about to tackle control arm ball joint replacement. I'm using Haynes for reference and they mention that the Octavia Mk2 comes with either cast or sheet steel control arms, and the tightening torque varies on which it is: How do I figure out which mine is? If that helps narrow it down it's a 2006 pre-facelift Mk2, 2.0 TDI BKD, DSG transmission.
